As shown in fig. 1-5, a frozen section sample holder comprises an outer disc 1 and an inner disc 2, wherein annular protrusions 3 are arranged on the upper sides of the outer disc 1 and the inner disc 2, and a clamping groove 101 is arranged on the outer side of the bottom of the outer disc 1 and is used for being connected with a fixing structure on a slicer; the middle part of the outer disc 1 is communicated, the inner disc 2 is arranged in the middle part of the outer disc 1 and is in sliding fit, and the inner disc can rotationally protrude out of the surface of the outer disc; four groups of sliding grooves 4 are formed in the inner wall of the outer disc 1, four groups of fixing columns 5 are arranged on the outer wall of the inner disc 2, and the fixing columns 5 can be in sliding fit in the sliding grooves 4; the chute 4 consists of an introduction part 41, a fixed part 42 and a sliding part 43, wherein a groove 6 is arranged at the top of the fixed part 42 and the top of the sliding part 43, and a side plate 7 is downwards extended from the right side of the groove 6 of the fixed part 42; the guiding part 41 and the fixing part 42 are on the same axis, the sliding part 43 is arranged at the upper right of the guiding part 41, the guiding part, the fixing part and the sliding part are positioned on the same ring surface, a notch 8 is arranged at the joint of the guiding part 41 and the fixing part 42, and the lower end of the sliding part 43 is communicated with the notch 8; the inner disc 2 is a cylinder with an opening at the bottom, an inner spring 9 and an outer spring 9 are arranged in the inner disc 2, the top of each spring 9 is fixed with the inner side surface of the top of the inner disc 2, and the bottom of each spring 9 is fixed with the chassis 10.

As shown in fig. 2-3, the lower end of the sliding portion 43 is provided with a triangular guide block 11 for guiding the fixing column into the sliding portion or the fixing portion.

As shown in fig. 2-3, a gap is left between the bottom of the side plate 7 and the hypotenuse of the triangular guide block 11, and the gap distance is larger than the diameter of the fixed column 5, so that the fixed column is not blocked when passing through the gap.

When the fixing column 5 is positioned on the top of the fixing portion 42 as shown in fig. 1, the outer surface of the inner disc 2 and the outer disc 1 are on the same level, and the flatness of the outer surface is ensured when large tissues are frozen.

As shown in fig. 2 to 3, the width of the introducing portion 41, the fixing portion 42, and the sliding portion 43 is identical to the diameter of the fixing column 5, and since the sample holder is vertically placed at the time of slicing, the fixing column is identical in size to the introducing portion, the fixing portion, and the sliding portion, and lateral displacement of the fixing column is prevented.
